Which of the following is NOT a role on the Ohio BPA executive board?

The role that is not part of the Ohio BPA (Business Professionals of America) executive board is the Region Coordinator. The executive board typically consists of positions that are crucial for overseeing the organization's operations, managing finances, and ensuring the proper documentation of events and activities. Positions such as Historian, Treasurer, and Parliamentarian serve specific functions: the Historian records the chapter's activities, the Treasurer manages financial matters, and the Parliamentarian ensures that meetings are conducted according to established procedures.

The Region Coordinator, while potentially a significant role at the statewide or local level, does not typically serve on the executive board itself. Instead, this function might exist to manage specific regions within the organization's framework but does not hold an executive position with the same level of authority or responsibility as the other roles identified. Being part of the executive board involves direct involvement in leadership and decision-making processes at the executive level of the organization.
